The following translators were not loaded due to errors:  ICERegions.htm:  has configuration information that his invalid.  Server Model SSI.htm:  has configuration information that is invalid.

I followed some advice to reset the workspace:

Go to Dreamweaver > Windows > Workspace layout > Reset “workspace name”

BUT it did not work.

The below solved the Dreamweaver translators were not loaded error for me:

1. Close Dreamweaver.
2. Open a Windows Explorer window.
3. In the Address bar enter %appdata% and click Enter.
4. Open the Adobe directory.
5. Open the Dreamweaver folder for the version of Dreamweaver you are using.
6. Dreamweaver CS4 users only – open the en_US directory.
7. Open the Configuration directory.
8. Locate the WinFileCache.dat file. There may be some other numbers appended to this filename.
9. Save the file somewhere as a backup just in case.
10. Delete the file from the Configuration directory.
11. Open Dreamweaver and try again.

Note: You do this at your own risk.

Hope this helps.
